In addition to the sterilization speed, sterilization effect is good, economic, environmental pollution of the pressure steam sterilization method, the most commonly used low-temperature sterilization method is ethylene oxide sterilization method.
Ethylene oxide sterilization is a low-temperature sterilization method, widely used in medical, food, cosmetics and other industries. Its main features are fast sterilization, good results, safe and reliable, economic and environmental pollution.
Ethylene oxide (EO) is a colorless, irritating odor gas with strong bactericidal ability. In a certain concentration, ethylene oxide can quickly kill bacteria, viruses, fungi and other microorganisms, to achieve rapid sterilization. The main principle of ethylene oxide sterilization method is to enter into the microbial cells through osmosis, destroying their vital substances and leading to the death of microorganisms.
Ethylene oxide can quickly kill all kinds of microorganisms, including heat-resistant bacterial spores, to ensure the sterilization effect. Ethylene oxide sterilization method has a shorter processing time, greatly improving work efficiency.
Ethylene oxide sterilization method features:
1, broad-spectrum sterilization: ethylene oxide has a broad-spectrum bactericidal effect on most microorganisms have a killing effect, including bacteria, viruses, fungi, spores and so on.
2, strong penetration: ethylene oxide has strong penetration, can penetrate the deep layers and crevices of the object to kill the microorganisms inside the object.
3, no residual toxicity: ethylene oxide will be decomposed into carbon dioxide and water after sterilization, and will not leave residual toxicity on the object.
4, suitable for a variety of items: ethylene oxide sterilization method is suitable for all types of medical devices, including metal, plastic, rubber, glass and other materials.
5, safe operation: ethylene oxide is a gas at room temperature and pressure, and requires a special sterilizing cabinet for sterilization, which is relatively safe to operate.
